Neuropathic pain is frequently comorbidity with cognitive deficits. Neuralized1 (Neurl1)-mediated ubiquitination of CPEB3 in the hippocampus is critical in learning and memory. However, the role of Neurl1 in the cognitive impairment in neuropathic pain remains elusive. Herein, we found that lumbar 5 spinal nerve ligation (SNL) in male rat-induced neuropathic pain was followed by learning and memory deficits and LTP impairment in the hippocampus. The Neurl1 expression in the hippocampal CA1 was decreased after SNL. And this decrease paralleled the reduction of ubiquitinated-CPEB3 level and reduced production of GluA1 and GluA2. Overexpression of Neurl1 in the CA1 rescued cognitive deficits and LTP impairment, and reversed the reduction of ubiquitinated-CPEB3 level and the decrease of GluA1 and GluA2 production following SNL. Specific knockdown of Neurl1 or CPEB3 in bilateral hippocampal CA1 in naïve rats resulted in cognitive deficits and impairment of synaptic plasticity. The rescued cognitive function and synaptic plasticity by the treatment of overexpression of Neurl1 before SNL were counteracted by the knockdown of CPEB3 in the CA1. Collectively, the above results suggest that the downregulation of Neurl1 through reducing CPEB3 ubiquitination and, in turn, repressing GluA1 and GluA2 production and mediating synaptic plasticity impairment in hippocampal CA1 leads to the genesis of cognitive deficits in neuropathic pain.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

OBJECTIVES: This study aimed to investigate the association between temporomandibular disorder (TMD) and insomnia using a two-sample Mendelian randomization (MR) approach. METHODS: Bidirectional MR analyses of two samples, TMD (n=377 277) and insomnia (n=375 359), were performed using genome-wide association study statistics published in the FinnGen database. Instrumental variables were first screened, and then inverse variance weighting (IVW) and MR-Egger were used as the main-effect assessment methods. Weighted median, weighted mode, and simple mode served as supplementary methods. We used IVW and MR-Egger to test for heterogeneity, as well as MR-Egger intercepts to assess the single nucleotide polymorphism (SNP) potential level of multiplicity effects. Sensitivity analyses were conducted based on leave-one-out to identify potentially influential SNPs. All analyses were conducted by using the two-sample MR R package and were considered statistically significant when P<0.05. RESULTS: MR analysis showed the presence of TMD on insomnia (OR=1.089, 95%CI: 1.017-1.166, P=0.014). Meanwhile, no effect of insomnia on TMD (OR=0.996, 95%CI: 0.964-1.029, P=0.816) was found. The sensitivity-analysis showed that no heterogeneity existed (P>0.05), and the presence of horizontal pleiotropy was not detected (P>0.05). Leave-one-out sensitivity analysis showed no single SNP, which may affect the causal relation. All findings indicated that the causal relationship between TMD and insomnia was not significantly affected by any individual SNP and that IV did not bias the results. CONCLUSIONS Results of MR analyses showed that TMD is a risk factor for insomnia, whereas insomnia is not a risk factor for TMD.

This paper Summarizes the experience of national renowned Chinese medical practitioner professor YANG Jun in treating lumbar pain with acupuncture and moxibustion.In the view of professor YANG Jun,the etiology of lumbar pain is various and the pathogensis is complex,of which mainly related to be invaded by external pathogen,meridians obstructing blockage,kidney deficiency due to elderly,less of moistening due to kidney essence deficiency,sprain caused by fall and strike,and blood stasis obstructing meridians,and the syndrome differentiation of lumbar pain usually involves cold-damp obstructing blockage,kidney essence deficiency,and blood stasis blocking collaterals.The waist is the residence of kidney,kidney meridian runs through the spine and connecting it to the kidney,the bladder meridian locates on both sides of the spine and connecting it to the kidney,the circulation of governor vessel(GV)to the kidney,so the pathogensis of lumbar pain is closely related to kidney,bladder meridian,governor vessel.The basic pathogensis of lumbar pain is meridian qiand blood stasis stagnation,or the meridian less of moistening due to kidney essence deficiency,both of which cause pain.The main therapeutic principle for lumbar pain should be focusing on mind-regulating and meridians-dredging,cold-dispersing and damp-removing,kidney-boosting and blood-activating,as well as collateral-unblocking and pain-relieving,combining the lumbosacral spinal tri-needling,regulating the bladder meridian with moxibustion and electro-acupuncture,thus to achieve the optimal quantitative and effective state.

The development and validation of clinical prediction models based on artificial intelligence (AI) and machine learning methods have become increasingly widespread. However, the prediction model bias risk and applicability evaluation tool developed in 2019 (i.e., PROBAST-2019) has shown significant limitations. Therefore, an expanded and updated version of the PROBAST-2019 tool was released in 2025, known as the PROBAST+AI tool. The tool is divided into two parts including model development and model evaluation. It aims to comprehensively and systematically evaluate potential methodological quality issues in model development, bias risks in model evaluation, and the applicability of models, regardless of the modeling method used. This paper provides a systematic interpretation of the PROBAST+AI tool's items and case analyses, with the aim of guiding and assisting researchers engaged in related studies and promoting the high-quality development of clinical predictive model research.

Background Environmental noise pollution is serious, and there are few studies on the effects of long-term noise exposure during sleep on cognitive function and possible biological clock mechanism. Objective To explore the cognitive impairment induced by noise exposure during sleep in mice and possible biological clock mechanism, and to provide a theoretical basis for the protection against noise exposure. Methods Twenty male C57BL/6J mice were randomly divided into a control group and a noise-exposed group, 10 mice in each group. The noise-exposed group was exposed to sleep-period noise using a noise generator for 12 h (08:00–20:00) per day for a total of 30 d. The calibrated noise intensity was set at 90 dB. No intervention was imposed on the control group. At the end of the noise exposure, cognitive function of mice was examined using the new object recognition experiment and the open field test, and the hippocampal tissue damage of mice were evaluated by Nissl staining, ionized calcium binding adaptor molecule 1 (Iba1) immunofluorescence staining, and real-time fluorescence quantitative PCR for inflammatory factors and biological clock genes. Oxidative stress indicators in the hippocampus of mice were also detected by assay kit. Results After noise exposure during sleep period, the results of new object recognition experiment showed that the discrimination index of mice in the noise-exposed group was 0.06±0.04, which was significantly lower than that of the control group (0.65±0.13) (P<0.05). The results of open field test showed that the central activity distance of the noise-exposed group was (242.20±176.10) mm, which was significantly lower than that of the control group, (1548.00±790.30) mm (P < 0.05), and the central activity time of the noise-exposed group was (0.87±0.64) s, which was significantly lower than that of the control group, (6.00±2.86) s (P < 0.05). The Nissl staining results showed that compared with the control group, neurons in the hippocampus of the noise-exposed mice were shrunken, deeply stained, disorganized, and loosely connected. The immunofluorescence results showed that microglia in the hippocampus of the noise-exposed mice were activated and the expression of Iba1 was significantly increased compared with those of the control group (P<0.05). The real-time PCR results of showed that the mRNA levels of the biological clock genes Clock, Per2, and Rev-erbα were significantly increased compared with those of the control group (P<0.05), and the mRNA level of Per1 was significantly decreased compared with that of the control group (P<0.05); and the mRNA levels of IL-18, IL-6, iNOS, and NLRP3 in the hippocampal tissues of mice were significantly increased compared with those of the control group (P<0.05). The results of oxidative stress evaluation showed that compared with the control group, reduced glutathione content was significantly reduced in the noise-exposed group (P<0.001). Conclusion Noise exposure during sleep period can lead to the destabilization of biological clock genes in hippocampal tissues and trigger hippocampal neuroinflammation, which can lead to the activation of microglia and cause cognitive impairment in mice.

Objective:To evaluate the efficacy and safety of brentuximab vedotin (BV) combined with rituximab and attenuated chemotherapy in the treatment of children with classic Hodgkin lymphoma (cHL).Methods:A prospective, non-randomized, risk-assigned study. Clinical data (including age, gender, B symptoms, bulky disease, CD30 and Epstein-Barr virus-encoded RNA(EBER) expression, clinical stage, risk stratification, etc.) of 28 intermediate to high-risk cHL children diagnosed and treated at Beijing Children′s Hospital Affiliated to Capital Medical University from October 2022 to May 2024 were collected. Immuno-targeted combined with attenuated chemotherapy was administered based on risk stratification and early treatment response. The patients were followed up until May 1st, 2024. The infusion reactions and adverse reactions after treatment were recorded.Results:In all 28 patients, there were 22 males and 6 females, the age was 12 (5,16) years, 16 cases (57%) presented with bulky disease and 10 cases (36%) with B symptoms. The most common pathological type was nodular sclerosis (14 cases, 50%). There were 7 cases of stage Ⅱ, 14 cases of stage Ⅲ and 7 cases of stage Ⅳ according to the Ann Arbor staging system. There were 5 cases in the intermediate-risk group and 23 cases in the high-risk group. EBER was positive in 20 cases (71%) and negative in 6 cases (21%), and CD30 antigen was expressed in tumor cells of all enrolled children. Treatment duration: 5 cases (18%) received 4 courses of treatment, 21 cases (75%) received 6 courses of treatment, and 2 cases (7%) received 8 courses of treatment, 25 cases (89%) achieved complete metabolism response (CMR) through early assessment after 2 courses of chemotherapy. The CMR rates were 100% in intermediate-risk group and 87% (20/23) in high-risk group, respectively. Four patients (14%) finally received residual field radiotherapy. Toxicities included grade Ⅰ-Ⅱ myelosuppression, early infusion reaction and mild peripheral neuropathy, only one case of grade 3 adverse events was recorded and did not affect sequential treatment. At the end of treatment and 3 months of follow-up, the levels of IgA, IgG and IgM were all decreased compared with the baseline before chemotherapy, and the total B cell count began to be lower than the level before chemotherapy at the early stage of treatment (after 2 courses). The total B cell count monitored during treatment was 50 (0, 101)×10 6/L and was 12 (0, 25)×10 6/L at the end of treatment. The follow-up time was 6 (3, 13) months, all 28 children had event-free survival and all achieved complete remission. At 6 and 9 months of follow-up, IgA, IgG, IgM and total B cell counts returned to pre-chemotherapy baseline levels, respectively. Conclusion:BV combined with rituximab attenuated chemotherapy has demonstrated efficacy and a tolerable safety profile in the treatment of cHL in children, and significantly reduce radiation rate.
